Conventional PAC system
The EAZ family of devices with a traditional design, manufactured and improved for many years, with proven functional and reliability properties.
Analog and binary signals from secondary circuits are directly connected to the relay housing, mounted in
control cabinets or on/behind boards using copper cables.
The devices can be equipped with communication ports compliant with IEC61850, IEC870-5-103 and CANBUS protocols.

UTX3 Series
UTX3 Series is a full-scheme distance protection device.
The basis for the reliable operation of the UTX3 series protection relays is the precise and fast measurement of voltages and currents and the implementation of the IEC61850, IEC870-5-103, CANBUS PPM2 communication protocols.
MSZ+LRW Device
UTX3vMSZ+, i.e. universal protection of busbars and Local Breaker Reserve automation.
UTX3vMSZ+ is a protection for busbars and LRW in various types of switchboards. Working with acquirers (µUTX3vL/SSZ) via a dedicated OPTO channel, it provides protection for up to 4 busbars in any configurations, supporting a maximum of 16 bays in which C&C acquirers are installed.
RNT Device
The transformer voltage regulator is intended for use in all regulation systems with an on-load tap changer on any high and medium voltage lines operating with a grounded, compensated or insulated star point.
The device ensures quick and reliable adjustment. Extensive functions of compensation for voltage drops, settings, calendar, event and disturbance recording and voltage quality recording ensure the implementation of even the most sophisticated applications.
SZR Device
It is intended for reserving power supplies in HV and MV switchboards in any configurations – including non-standard ones. It ensures: fast, selective and reliable switching in the event of any type of disturbance: (voltage loss or circuit breaker tripping).
In the HV switchgear it can work as an ATS of a line string, controlling 3 circuit breakers in the lines and the crossbar. In addition to the standard types of reserves, the device can implement any type of reserve, controlling up to 8 voltage groups and up to 15 switches.
XSERWER Device
XSERWER is an industrial computer designed to collect information from protection devices, regulators, recorders and other station devices. It acts as a hub and protocol converter. The XSERWER supports DNP3, IEC 60870-5-103, IEC61850 protocols and the company’s CC-Bus communication protocol.
ARCHI Device
ARCHI 9000/900 is a digital disturbance recording system. The device digitally records analog and binary measurement signals occurring in power facilities for subsequent analysis using an appropriate program. It is a completely scalable device with the possibility of expansion to 128 analog signals, 32 frequency measurement signals and up to 720 binary inputs. The enormous recording possibilities are extended with modules enabling precise signaling of normal and emergency operating states.
CSS Device
CSS 4E is a freely programmable, scalable device that signals the occurrence of a specific state on binary inputs using a panel of light indicators and a set of relay outputs. Received signals can be grouped and individually assigned to optical indicators, relay outputs or reset inputs.
As standard, CSS 4E also has the ability to record, duplicate and translate signals, make them logically dependent on each other, and allows for the implementation of the functions of a field controller with three-valued logic.
HR8A Device
HR8A-400V fast power relay relays are intended for use in all types of DC and AC circuits. They combine the best features of traditional electromechanical relays – minimal contact resistance, and modern semiconductor elements – high speed of operation. The short switch-on time, below 0.3 ms, and the ability to disconnect inductive circuits with L/R=40ms and current up to 8A/220V DC make them suitable for use, especially in control circuits of power system switches.
